## Discrepancy

ON APPROACH, UPON SELECTING THE LANDING GEAR HANDLE DOWN, THE HYDRAULIC PUMP RAN AS NORMAL BUT THE GEAR DID NOT CHANGE POSITION.  THE HYDRAULIC CONTROL BREAKER F-7 WAS TRIPPED, WHEN RESET AND PROCEDURE REPEATED IT TRIPPED AGAIN.  WITH BREAKER STILL TRIPPED, GEAR HANDLE WAS SELECTED DOWN THEN BREAKER F-7 WAS CLOSED AND GEAR CAME DOWN NORMALLY AND BREAKER DID NOT TRIP.  MAINTENANCE REPLACED LANDING GEAR CONTROL HANDLE.  SECURITY AND OPS CHECKS GOOD.
